摘要 对Tiltdepth方法进行了理论模型研究,得出该方法在判断地质体的埋藏深度上具有良好的效果,在确定深部场源的埋藏深度上也有优势,故将确定深部场源的埋藏深度延伸到确定基底的埋藏深度,为实际资料处理提供了理论依据保障。Tiltdepth方法应用到实例中,发现高频成分的存在对基底深度的判断有一定影响,故利用迭代法向上延拓方法滤除掉高频成分后,取得了理想效果,给实际的航磁资料处理带来方便和快捷。

Abstract: The theoretical model study of the Tiltdepth method shows that this method is effective in judging the buried depth of
the geological body, and also has superiority in determining the buried depth of the deepseated field source. The determination of
the buried depth of the deepseated field source is hence extended to the determination of the buried depth of the basement with
the purpose of providing theoretical guarantee for practical data processing. The application of the Tiltdepth method to practice
revealed that the existence of the highfrequency component had some influence on the judgment of the basement depth. The upward
continuation with the iterative method was therefore used to eliminate the highfrequency component, with ideal result attained.
The achievements obtained in this study have brought easiness and rapidness to aeromagnetic data processing. |
